I am trying to build a linear model(multiple linear regression). In that, I have multiple variables which are not significant. My output is somewhat like this-
I am trying to remove the variable house_typeBrick_Panel by-
model2<- update(model, ~. - house_typeBrick_Panel)
But it's not updating and still the variable house_typeBrick_Panel is there.
Can anybody guide me how to update my model?
